Measuring LEDs

The LED-PS Power Supply works with our spectrometers and the FOIS-1 Fiber Optic Integrating Sphere for spectroradiometric and color measurements of LEDs. The LED-PS unit has easy-to-reach electrical connectors for mounting LEDs that are 9.52-mm diameter or smaller with 2.77-mm lead spacing.

Adjustable Drive Current

The LED-PS Power Supply provides three useful functions. The LED-PS holds the LED in place, powers the LED, and displays the LED’s drive current. The drive current is adjustable, with a digital display to indicate the current level. Use the adjustable drive current feature to increase or decrease and LED's current up to 50 mA. With the LED-PS-NIST, the current meter is calibrated against a NIST-traceable standard. For more on Spectroradiometric Measurements, click here.

Integrating Sphere for 360° Emission Collection

Powered by the LED-PS Power Supply, the LED is inserted into the 9.5-mm diameter port of the FOIS-1 Fiber Optic Integrating Sphere, which has a 360° field of view. A P400-2-VIS-NIR Optical Fiber collects the light from the FOIS-1 and delivers it to the USB2000 Spectrometer.
